ABSTRACT Water quality models are often applied to support the definitions for water resources planning and management. This process requires appropriate data calibrate make required verification validation analysis. However, in some case studies, there is not enough run a complex model whatever system, being river or reservoir. In context of scarce data, search simple an alternative comprehend...

This paper examines and ranks restoration alternatives for improving fish habitat by evaluating tradeoffs between fish production and restoration costs. Optimization modelling is used to maximize out‐migrating coho salmon (Oncorhynchus kisutch) from a natal stream and is applied as a case study in California’s Shasta River. Restoration activities that alter flow and water temperature conditions...

Ecological assessment of large rivers such as the Danube is a challenging task. Eutrophication was reported one main drivers that structure aquatic communities in basin. Due to their sedentary nature, relatively slow growth/ long life spans, and engineering role ecosystems, macrophytes are widely used detection nutrient enrichment. In this study, macrophyte presence-absence data within 3 km rea...

Abstract The forecast analysis of the exposure to contamination risk in a water distribution network requires increasing quality applied input/outputs modeling. This need involves using non-traditional models responding increasingly high computation requirements. In this scenario, Cellular Automata paradigm represents new frontier with considerable potential. Specifically, paper describes Euler...

Modelling is an effective tool to investigate the ecological state of water resources. In developing countries, the impact of sanitation infrastructures (e.g. wastewater treatment plants) is typically assessed considering the achievement of legal physicochemical quality standards, but ignoring the ecological water quality (EWQ) of the receiving river. In this paper, we developed a generic integ...
